The FAG HC71910-C-T-P4S-UL is a high-precision hybrid angular contact ball bearing designed for demanding spindle applications. Featuring ceramic balls and steel rings, this hybrid design offers superior performance, including higher speed capabilities, reduced friction, and enhanced rigidity compared to traditional steel bearings. It has a 50 mm bore diameter, 72 mm outer diameter, and a 12 mm width. The bearing is characterized by a 15° contact angle (C), a textile laminate cage (T), and P4S precision class, indicating very high accuracy. The 'UL' designation signifies a universal arrangement for paired mounting with a light preload, making it suitable for high-speed machine tool spindles and other precision rotating equipment.
